Histopathological Effect of Annona Muricata Fruit Extract on Methyl nitrosourea -Induced Mammary Gland Carcinoma in Female Albino Mice

The Annona muricata (Family-Annonaceae) fruit contain annonaceous acetogenins which have an effect on cancer cell as reported in many research studies. This study was aimed to evaluate the effect of methanolic fruit extract of Annona muricata (MFEAM) on breast cancer histology and invasive cell of MNU-induced breast cancer mice. Fifty female albino mice were divided into five groups (of ten each): control; MNU-induced breast cancer; MNU-induced breast cancer + (MFEAM) 200 mg/kg, MNU-induced breast cancer + (MFEAM) 300 mg/kg and MNU-induced breast cancer + (MFEAM) 500 mg/kg. The research indicates that breast cancer invasive ductal carcnoma (IDC) developed in the MNU-induced breast cancer group. The control group showed normal duct structure. The (MFEAM) -treated group showed lower invasive (DCIS) compared with the untreated cancer group. We concluded that (MFEAM), that improved the histological changes of breast cancer-induced MNU. Also (MFEAM) reduced proliferative epitheal cell of breast cancer-induced MNU and the most effective dose was 300 mg/kg. The present study concluded that the methanol extracts derived from Annona muricata fruit potentially exhibit antitumor activity.              The control group showed normal duct structure. The (MFEAM) -treated group showed lower invasive (DCIS) compared with the untreated cancer group, We concluded (MFEAM) that improved the histological changes of breast cancer-induced MNU. Also (MFEAM) reduced proliferative epitheal cell of breast cancer-induced MNU and the most effective dose in 300 mg/kg.
